Plain English Translation

A medium discharging device is designed to extend a receiving tray for accommodating discharged media, such as paper, in a compact and adjustable manner. The device includes a discharging unit that propels the medium in a specific direction and a medium receiving tray that collects the discharged medium. The receiving tray features a base tray and three slidable units stacked in sequence: a first slidable unit connected to the base tray, a second slidable unit connected to the first, and a third slidable unit connected to the second. Each slidable unit can transition between an accommodated state, where it is retracted, and an extended state, where it is pulled outward in the medium discharging direction, increasing the tray's length. The third slidable unit includes a rotatable stopper to secure the extended position. When fully extended, the first, second, and third slidable units progressively extend further in the discharging direction, maximizing the tray's capacity while maintaining a compact retracted state when not in use. This design optimizes space efficiency in devices like printers or copiers by allowing the tray to extend only when needed.

Claim 2

A medium discharging device comprising: a discharging unit that discharges a medium towards a medium discharging direction in which the medium is discharged; and a medium receiving tray that receives the medium discharged by the discharging unit, wherein the medium receiving tray includes a base tray; a first slidable unit that is slidably connected to the base tray, and that is configured to have a first accommodated state, and a first extended state, wherein when the first slidable unit is slid into the first extended state by pulling the first slidable unit in the medium discharging direction, the first slidable unit is located further in the medium discharging direction than when the first slidable unit is in the first accomodated state; and a second slidable unit that is slidably connected to the first slidable unit, and that is configured to have a second accommodated state, and a second extended state, wherein when the second slidable unit is slid into the second extended state by pulling the second slidable unit in the medium discharging direction, the second slidable unit is located further in the medium discharging direction than when the second slidable unit is in the second accomodated state; a third slidable unit that is slidably connected to the second slidable unit, and that is configured to have a third accommodated state, and a third extended state, wherein when the third slidable unit is slid into the third extended state by pulling the third slidable unit in the medium discharging direction, the third slidable unit is located further in the medium discharging direction than when the third slidable unit is in the third accomodated state; and a stopper that is rotatably attached to the third slidable unit, wherein the base tray is fixed to at least a portion of the medium discharging device.

Plain English Translation

A medium discharging device is designed to handle printed or processed media, such as paper, by extending a receiving tray to accommodate varying lengths of output. The device includes a discharging unit that propels the medium in a specific direction and a medium receiving tray with multiple slidable extensions. The base tray is fixed to the device, while the first slidable unit connects to the base tray and can slide outward in the medium discharging direction to extend the tray. The second slidable unit connects to the first unit and can further extend outward, followed by the third slidable unit, which connects to the second unit and extends even further. Each unit transitions between an accommodated (retracted) state and an extended state, allowing the tray to expand incrementally. A stopper is rotatably attached to the third slidable unit, likely to secure the extended position or prevent over-extension. This design enables the tray to adjust its length dynamically, accommodating different media sizes without manual adjustments, improving usability and space efficiency in printing or document processing systems.

Claim 3

Original Legal Text

3. A medium discharging device comprising: a discharging unit that discharges a medium towards a medium discharging direction in which the medium is discharged; and a medium receiving tray that receives the medium discharged by the discharging unit, wherein the medium receiving tray includes a base tray; a first slidable unit that is slidably connected to the base tray, and that is configured to have a first accommodated state, and a first extended state, wherein when the first slidable unit is slid into the first extended state by pulling the first slidable unit in the medium discharging direction, the first slidable unit is located further in the medium discharging direction than when the first slidable unit is in the first accomodated state; and a second slidable unit that is slidably connected to the first slidable unit, and that is configured to have a second accommodated state, and a second extended state, wherein when the second slidable unit is slid into the second extended state by pulling the second slidable unit in the medium discharging direction, the second slidable unit is located further in the medium discharging direction than when the second slidable unit is in the second accomodated state; a third slidable unit that is slidably connected to the second slidable unit, and that is configured to have a third accommodated state, and a third extended state, wherein when the third slidable unit is slid into the third extended state by pulling the third slidable unit in the medium discharging direction, the third slidable unit is located further in the medium discharging direction than when the third slidable unit is in the third accomodated state; and a stopper that is rotatably attached to the third slidable unit, wherein the stopper is rotatably attached to the third slidable unit so to rotate in the medium discharging direction when the stopper rotates away from the third slidable unit.

Plain English Translation

A medium discharging device is designed to extend the reach of a medium receiving tray to accommodate varying discharge distances. The device includes a discharging unit that propels a medium, such as paper, in a specific direction. The medium receiving tray consists of a base tray and three slidable units stacked in sequence. The first slidable unit connects to the base tray and can slide between an accommodated state and an extended state, moving further in the discharge direction when extended. The second slidable unit connects to the first unit and operates similarly, sliding between its own accommodated and extended states. The third slidable unit connects to the second unit and also slides between accommodated and extended states. A stopper is rotatably attached to the third unit, designed to rotate in the discharge direction when moved away from the unit. This multi-stage sliding mechanism allows the tray to extend incrementally, providing flexibility in positioning the receiving surface relative to the discharging unit. The stopper ensures stability and controlled movement during extension. This design addresses the need for adjustable medium support in devices like printers or copiers, where varying discharge distances require adaptable tray configurations.

Plain English Translation

A medium discharging device is designed to handle printed or discharged media, such as paper, by extending a receiving tray to accommodate varying lengths of output. The device includes a discharging unit that propels media in a specific direction and a medium receiving tray with multiple slidable units. The base tray supports a first slidable unit, which can be pulled outward to extend the tray further in the discharge direction. Attached to the first slidable unit is a second slidable unit, which can also be extended outward. A third slidable unit is connected to the second unit and can be extended further. Each slidable unit transitions between an accommodated (retracted) state and an extended state, allowing the tray to adjust its length dynamically. The third slidable unit includes a rotatable stopper that, when in an extended position, stands perpendicular to the tray to prevent media from sliding off. This design ensures media is securely held regardless of the tray's extension state, improving usability in devices like printers or copiers where output length varies. The multi-stage extension mechanism optimizes space efficiency while accommodating different media sizes.
